' To all whom t may concern.:

r axle or spindle 7, upon which vare rotatably' mounted traction wheels 8. Disposed pref-V Be it known that I, ADOLPH SCHMIDT, a

.citizenr of the United States, residing at Hastings, in the county of Adams and State of Nebraska, have invented certain new and useful Improvements in Plows, of which the following is la specilication. u

My invention relates to plows and has particularreference to apparatusof this-character which is driven by means of an engine or other prime mover.

An important object of this invention is to provide apparatus of the above mentioned character, which is easy to operate, and is provided with novel means of raising and lowering the plow beams whereby the Aplow shares carried thereby will be moved into and out of engagement with the soil.

A Afurther object o this invention is to provide apparatus of the above mentioned character, which is simple in construction, easy to loperate, durable and comparatively cheap to manufacture.

Other objects and advantages of this invention will be apparent during the course of the following description. y

In 'thedrawinga forming Va part of this specilication and in which like numerals are employed to designate like parts throughout the same, Figurel is a plan view of the apparatus, and, Fig. 2 is a side view of the same.

In the drawings, wherein for the purpose of illustration, I have shown a. preferred embodiment of my invention, the numeral 3 designates spaced longitudinal beams of the main frame, which are connected atthei'r rear ends by a transverse beam 4 and near and spaced from their forward endsby a transverse beam 5, as shown. Connected with the forward ends of the longitudinal beams A3 are brackets 6, for receiving an erably inwardly of the traction wheels 8 are large gear wheels 9, rigidly connected therewith by means of clamps 10, as shown. li desired, these gear wheels may be cast in tegral with the traction wheels 8. Disposed rearwardly of the brackets Gare brackets 11, receiving a transverse shaft 12, upon which are rigidly mounted small gear wheels 13, which engage the large gear wheels 9, asA

shown. Disposed near the rear transverse beam 4 is a ltransverse. platform 11i, rigidly connected with the longitudinal beams 3 by Specification of Letters ferent.

Patented Deca any suitable means. Suitably mounted upon this plat-form is a prime mover lwpreter ably) an internal combustion engine of any well known or preferred type.4 This engine drives a sprocket wheel 1 6, engaged by a sprocket chain 17, which entends forwardly to engage a sprocket wheel 18,7whifeh is rigidly mounted upon the transverse shaft lil.

The rear end ofnthe main frame is supported by a steering wheel 19, provided with an outwardly extending annular fiange S30, as shown. This steering `wheel is rotatably mounted within a bifurcated standard 2r.,

with which is ri,gidly',eonnected an upstand. ing cylindrical steering' post 22.

This steen ing'post isyinurnaled through a bracket wh'ichwisvrrgidiy attachedjp the rear trama verse beam l. Connected with the upper end of the steering post 22 is a cra-nk or han-- dle 24, as shown. The steering1 post er,"- tends through a suitable openingr 'formen in a rearwardly extending' plat-form or support Q5, which is rigidly attached tothe rear transverse beam 1lby any suitable meana Connected with the platforinor support 25 is a suitably stiff springr arm Q6, havingu con nectiou at its upper end with 27.

Disposed below and between the longitm dinal beams 3 are transversely spaced plow beams 28, 29 and 3G, of diilj'erent lengths, as shown. These plow beams have plow shares 30a connected with their rear depending ends, as shown. Connected with the forward end of the plow beams 28 and 30 are n hook-shaped brackets 31,which engage upon the axle 7, as shown. The hooi: portipns or lthe brackets 31 are disposed between rings 32, which are clamped to the arde 7, bv

means of ,boltsy or the like.` Thet'orward ends of the beams 28 and 30ers connected bya transverse strip#r 34, as shrwfn. r` This transverse strip is also connected with the forward end of the plow beam 29. The rear ends of the plow beams 28, 29, and 30 are connected by a diagonal rod or brace shown. It is thus seen that the pfow beams 28, Q9 and 30 are rigidly connected so that the same may be swung in a vertical pl as an integral structure. Connected the forward portion of the plow beam .1H and the -rear portion of the plow beam 9.-@ are bearings or brackets 36, which i forward bail crankshaft Sil Thi..

shaft has its ends journaled within venti bolts 44, adapted to t within spaced superposed openings 45, as shown. At one end, the crank-shaft 42 is provided with an upstandin arm or crank 46, having pivotal connection with a reach rod 47, which pivotally connected with the upper end of a crank 43, carried by a rock-shaft 49. This rockshaft is journaled through fixed bearings 50 or the like. At its inner end, the

rock-.shaft 49 is provided with an upstanding crank 51, to which ispivotally connected a link 52, having pivotal connection with an upstanding lever 53. This lever is pivoted, as shown at 54 and is provided with latch means 55, to engage a fixed toothed segment 56, whereby the lever 53 may be securely held in adjustment at different angular positions, against movement in one direction. Connected with the left longitudinal beam 3 is a stub-shaft or axle 57, upon which is rotatably mounted a third-wheel 5S aiding in the support of the rear end of the main frame, without preventing the same being steered by the wheel 19.

The operation of the apparatus is as follows The operator who sits within the seat 27 starts the engine 15, which rotates the sprocket wheel 1G., such rotation being imparted'to the traction wheels 8 for propel ling the apparatus. The apparatus is steered by turning the crank or handle 24. By providing the wheel 19 with the annular flange 20 it is more capable of steering the apparatus during the travel thereof. When it is desired to raise the plow shares 30n out of engagement with the soil, the operator takes hold of the lever 53 and first operates the latch means 55 to release the lever, subsequent to which the same may be swung 1n proper direction for turning the bail crank- ,shaft 42, whereby the plow beams will be elevated. When this bail crank shaft 42 is swung upwardly, it raises the rear end of the low carrying beam 28, the plow carrying eams 29 and 30, moving upwardly with it.. The bail crank shaft 37 is swung upwardly by the teeth carrying beams 28, 29 md 30, the same serving to pivotally con I neet these beams with the longitudinal frame beams 3. It is obvious that the hooks 31 serve to pivotally connectv the forward ends of the teeth carrying beams 28 and 30 with the axle 7, to allow the same to swing in a vertical plane and be disconnected from the axle by an upward movement of said hooks 31. f,

It is to be understoodthat the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that certain changes in the shape, size and arrangement of parts may be resorted to without departing from the lspirit of the invention or the scope of the subjoined claims.

Having described my invention, I claim 1. The combination with a wheeled frame' including a transverse member, of a plurality of plow share carrying beams extending longitudinally thereof, an upstanding hook connected 'with the forward end of each plow share carrying beam and fitting over the transverse member, and a bail crank shaft pivotally connected with the wheeledl frame and with certain of the plow share carrying beams.

2. The combination with a wheeled frame including a transverse member, of a plurality of plow share carrying beams extending longitudinally thereof, a plurality of pairs of spacedI rings rigidly mounted upon the transverse member, upstanding hooks connected with the forward ends of certain of the plow share carrying beams and passing over the transverse member between the spaced rings, a bail crank shaft pivotally connected with the wheeled frame and with certain of the plow share carrying beams, and means to turn the bail crank shaft.

3. In apparatus of the character described, the combination with a wheeled frame including a forward transverse memberofa plow share carrying beam disposed therebelow and extending longitudinally thereof, an upstanding hook connected with the for ward end of the plow share carrying beam and passing over the transverse member, a transverse bail crank shaft pivotally connected with the wheeled 'frame and with the plow share carrying beam, and means to turn the bail crank shaft and lock the same in adjustment at desired positions.

In testimony whereof I aliixmy signature in presence of two witnesses.

ADOLPII SCHMIDT.
